Effect of arthroscopic surgery combined with platelet-rich plasma in the treatment of discoid meniscus injury of knee joint and its influence on serum inflammatory factors

Abstract

This study was to observe the effect of arthroscopic surgery combined with platelet-rich plasma (PRP) in the treatment of discoid meniscus injury of knee joint and its influence on serum inflammatory factors. A total of 80 patients with discoid meniscus injury in our hospital from June 2014 to June 2016 were enrolled and divided into study group and control group randomly with 40 patients in each group. The control group was treated with arthroscopy alone, and the study group was treated with arthroscopy combined with PRP. The clinical efficacy of the two groups was observed, and the Lysholm scores, Knee injury and Osteoarthritis Outcome Score (KOOS scores), and serum inflammatory factors (IL-1, TNF-α, and IL-6) were compared between the two groups before and after treatment. Six months after the treatment, the improvement rate, defined as (Excellent + Good)/total*100, of the study group was 97.5%, significantly higher than that of the control group, which was 87.5% (P < 0.05); before treatment, there was no significant difference in both Lysholm scores and KOOS scores between the two groups (P > 0.05); and 6 months later, the Lysholm scores and KOOS scores in the two groups were both significantly higher than those before, and the scores in the study group increased more significantly compared with those of the control group (P < 0.05); the values of serum IL-1, TNF-α, and IL-6 in the two groups were both significantly lower than those before, and the values in the study group decreased more significantly compared with those of the control group (P < 0.05). In conclusion, arthroscopic surgery combined with PRP therapy can effectively improve the clinical symptoms and reduce the level of serum inflammatory factors in patients with discoid meniscus injury of the knee, which is worthy of promotion and application.
